New User Registration
In recent development the following modules have been moved from web_ui to their own place: register, and the required component activation changed accordingly.
For AccountManager versions before acct_mgr-0.4 use the following setting instead of the settings mentioned later on:
[components] acct_mgr.web_ui.RegistrationModule = enabled acct_mgr.web_ui.EmailVerificationModule = enabled
Enables users to register a new account. It adds a “Register” link on the same menu bar as the “Login” link.
[components] acct_mgr.register.RegistrationModule = enabled
Warning: You must enable one of the password storage modules for the Registration Module to work.
Note: You must not enable ignore_auth_case in trac.ini as otherwise this module won’t work. [Update: This doesn't apply to trunk branch anymore. Use a revision at changeset  or later to lift this limitation.]
If you enable this, users will be sent an email with a verification code to enter, to approve it is really their own email address:
[components] acct_mgr.register.EmailVerificationModule = enabled acct_mgr.notification.AccountChangeListener = enabled
Until they entered the verification code on the URL sent with the email, their permissions will be restricted (even if they have the TRAC_ADMIN privilege, they won't be able to access anything exceeding the standard privileges of authenticated users). Update: After changeset  ACCTMGR_ADMIN (and TRAC_ADMIN, as it inherits it among all other privileges) won't be bothered with the verification procedure.
This has been added as a strict requirement now as suggested by ticket #5509 to trunk code with changeset , but was not enforced before, so verification only happened, if an email had been specified on registration. In other words, if some user registered w/o specifying an email address, this was possible and an unrestricted account was created without requiring further actions.
Note that if you don't want to enforce entering a valid email on registration, you may want to disable this component. An option
[account-manager] verify_email = false
As shown in the configuration above, you'll have to enable the accountchangelistener component as well. Without it, verification emails will be silently ignored (but the web-UI will still say they got sent!).
Modular Registration Checks
Since acct_mgr-0.4 you have control over number and order of registration checks through an option in trac.ini (showing default value here):
[account-manager] register_check = BasicCheck, EmailCheck, RegExpCheck, UsernamePermCheck
This is an OrderedExtensionsOption. Consequently listed items must be enabled components, that implement the IAccountRegistrationInspector interface (see following section for details).
class IAccountRegistrationInspector(Interface): """An interface for Components, that wish to participate in examining requests for account creation. The check method is called not only by RegistrationModule but when adding new users from the user editor in AccountManagerAdminPanels too. """ def render_registration_fields(req, data): """Emit one or multiple additional fields for registration form built. Returns a dict containing a 'required' and/or 'optional' tuple of * Genshi Fragment or valid XHTML markup for registration form * modified or unchanged data object (used to render `register.html`) If the return value is just a single tuple, its fragment or markup will be inserted into the 'required' section. """ def validate_registration(req): """Check registration form input. Returns a RegistrationError with error message, or None on success. """

There are some 3rd-party extensions to the registration module/process:
- GlobalRegisterPlugin - no check, just adds a hint about user store being shared for all Trac environments at the same host
- RecaptchaRegisterPlugin - reCAPTCHA support for the registration page
- SimpleCaptchaPlugin - captcha driven by Skimpy Gimpy (uses an alternative extension point interface)
- TracCaptchaPlugin - modular reCAPTCHA support, not only for the registration page
